Techniques in Electromanometry of the Upper Esophageal Sphincter

Abstract

The various pull-through techniques used to measure pressure and length of the upper esophageal sphincter have not been studied in depth. Because of the importance of obtaining further information about these techniques, a group of 25 dogs was submitted to upper esophageal sphincter pressure and length measurements by three different pull-through techniques (two of the continuous type and one of the station type), each with three replications per animal, to determine possible differences among techniques. A single introduction provided reliable results, with no sequential effect of the measurements or of any one technique on resting pressure. However, each technique yielded different sphincter lengths, higher values being obtained when the continuous techniques were used.

Functional evaluation of the ileocolic sphincter transplanted to the neck using microsurgery technique: a manometric study in dogs *

“…Dogs were used in this experiment, because they are easy to obtain, they have been studied in our laboratory previously 11 , 12 and the vascular pedicle dimensions allow vascular anastomoses without special equipment.…”

“…The manometric studies were performed using a three‐lumen recording catheter, a continuous infusion of distilled water, external pressure transducers, and a recorder apparatus. The intermittent pull‐through technique was used with continuous infusion of distilled water (2.5 ml/min) 11 . 12…”

Avaliação manométrica do esfíncter inferior do esôfago de coelhos submetidos a fundoplicatura total e parcial

“…A manometria esofágica foi realizada segundo a técnica de tração intermitente da sonda 10,11,12 . A sonda foi introduzida até o estômago e a seguir tracionada de meio em meio centímetro até atingir o EIE e o corpo esofágico, aguardando-se a estabilização do registro após cada tração 13 .…”
